Habitat Loss, Fragmentation, and Restoration

  journal={Restoration Ecology},
The loss and fragmentation of habitat is a major threat to the continued survival of many species. We argue that, by including spatial processes in restoration management plans, the effects of habitat loss and fragmentation can be offset. Yet few management plans take into account spatial effects of habitat conservation/restoration despite the importance of spatial dynamics in species conservation and recovery plans. Tilman et al. (1997) found a “restoration lag” in simulations of species… 

Local habitat restoration in streams: Constraints on the effectiveness of restoration for stream biota

Five issues that are likely to have a direct bearing on the success, or perceived success of local habitat restoration projects in streams are discussed and how the factors affect populations, communities and ecosystems are highlighted.

Spatial and Temporal Considerations in Restoring Habitat for Wildlife

It is recommended that managers identify the wildlife species they want to target for restoration efforts, consider the size and landscape context of the restoration site and whether it is appropriate for the target species, identify the habitat elements that are necessary for thetarget species, develop a strategy for restoring those elements and the ecological processes that maintain them, and implement a long-term monitoring program.

Forest degradation, conservation and restoration in Sweden

Forest ecosystems in Sweden are dynamic, and many species rely on natural disturbance regimes. Today, most structurally complex forests have been converted into even-aged stands of predominantly

Designing a network for butterfly habitat restoration: where individuals, populations and landscapes interact

Summary 1 Restoring biologically appropriate habitat networks is fundamental to the persistence and connectivity of at-risk species surviving in highly fragmented environments. For many at-risk

Reptiles in restored agricultural landscapes: the value of linear strips, patches and habitat condition

Habitat restoration, including revegetation of linear strips and enlargement of remnant patches, may benefit native fauna in highly fragmented landscapes. Such restoration has occurred around the

The restoration of biodiversity: where has research been and where does it need to go?

It is suggested that the high level of variation seen in restoration outcomes might be explained, at least in part, by the contingencies placed on site-level restoration by landscape and historical factors and presented a number of avenues for future research to address these often ignored linkages in the biodiversity restoration model.

Habitat restoration deadlines for a spatially implicit Levins/Tilman population model modified by an Allee effect are determined and it is found that restoration deadlines depend nonlinearly on initial, temporary, and final habitat destruction values.

Habitat loss accelerates for the endangered woodland caribou in western Canada

Habitat loss is often the ultimate cause of species endangerment and is also a leading factor inhibiting species recovery. For this reason, species‐at‐risk legislation, policies and plans typically

‘Grassland restoration aims to recover the diversity and ecosystem services that grasslands provide’ (Blair et al. 2014). Those aims include native insects themselves (diversity) and services such as



Relative Effects of Habitat Loss and Fragmentation on Population Extinction

It is suggested that details of how habitats are arranged cannot usually mitigate the risks of habitat loss, and conservation efforts should be aimed foremost at stopping habitat loss and at habitat restoration.

Considerations of scale in habitat conservation and restoration

The design of effective habitat management strategies will require increased attention to the scale-related problems presented by large systems, including the appropriate scale of observation relative to habitat management objectives, the linkages among habitat structures and processes, and monitoring at multiple scales.

Habitat Destruction and the Extinction Debt Revisited

It is concluded that the extinction-debt effect is real and arises in three different models, but relating the models to real-world conservation problems must be done with care.


It is shown that for such species habitat destruction can lead to an increase in the absolute abundance of the inferior competitor, which is more than compensated for by the reduced competition with the superior species, which suffers even more from habitat destruction because of habitat destruction.

The effect of habitat destruction pattern on species persistence : a cellular model

It is shown that the pattern of habitat destruction affects the minimum amount of habitat required to avoid extinction, and if intensity of habitat loss occurs along a gradient, rather than at random, species persist until a much greater overall habitat loss has occurred.

Habitat destruction and the extinction debt

A model is described that explains multispecies coexistence in patchy habitats and which predicts that their abundance may be fleeting, a future ecological cost of current habitat destruction.

Biological Corridors: Form, Function, and Efficacy

The indusion of corridors in reserve designs has become an importa nt conservation tactic for protecting biological diversity and was motivated by theoretical and empirical observations demonstrating that increased interchange of corridors increases the connectivity of otherwise isolated patches.

The Promise and Limitations of Spatial Models in Conservation Biology

Given the shakiness of spatial models as a foundation for specific conservation recommendations, it is concluded they may be more useful as a tool for exploring the design of spatially-structured monitoring schemes, so that management mistakes might be detected before they become irreversible.

Analysis of data from a 10-yr field study and simulation models suggest that the Acorn Woodpecker population persists only because it is part of a larger "metapopulation," andBecause it is regularly rescued from extinction by immigration from other, independently varying, populations.

Population size dependence, competitive coexistence and habitat destruction

The results suggest that population size–extinction relationships may play a large role in competitive coexistence, especially in the cellular automata models.
